Everyone except external users and Everyone claims added by default when new site is created in SPO

Occasional Contributor



I have created sites( private team site, public team  site and communication site) in my tenant, and noticed that below users/groups added by default.  I can see all these entries in user info list or all people list(_layouts/15/people.aspx?MembershipGroupId=0)

  1. Everyone except external users
  2. Everyone
  3. Site owner/creator name
  4. O365 group members if it is group site

I understood the purpose of 3 & 4 but not clear why 1&2 are added by default to the sites.


Please explain why 1&2 are added in to private group site when site is created.


Thanks in advance.
